In the circuit of Fig., assume that the diodes are ideal and the meter is an average indicating ammeter. The ammeter will read

Find the input resistance $${R_{in}}$$ of the infinite section resistive network shown in Fig.

The open circuit impedance matrix $${Z_{OC}}$$ of a three-terminal two-port network with A as the input terminal, B as the output terminal, and C as the common terminal, is given as $$$\left[ {{Z_{OC}}} \right] = \left[ {\matrix{ 2 & 5 \cr 3 & 7 \cr } } \right]$$$

Write down the short circuit admittance matrix $${{Y_{SC}}}$$ of the network viewed as a two-port network, but now taking B as the input terminal, C as the output terminal and A as the common terminal.

The trigonometric Fourier series of an even function of time does not have the
